EXTENSIBLE CURTAIN-ROLLER.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed March 10, 1914. Serial No. 823,817.

To all whom it may concern:

Be it known that I, HENRY KLEIN, citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Extensible Curtain- Rollers, of which the following is a specification.

My invention relates to extensible rollers for curtain shades and the like.

As an object of the invention, I provide an extensible roller wherein a longitudinally divided curtain may be adjusted relatively to the window over which it is suspended, said curtain and roller embodying novel features of construction and arrangement to be hereinafter fully disclosed.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a front elevation, partly broken away, of a curtain roller constructed in accordance with the present invention, said roller being associated with a longitudinally divided curtain shade; Fig. 2 is a detail perspective view illustrating the end formation of one of the roller sections; Fig. 3 is a similar View illustrating the end formation of the other of the said roller sections; Fig. 4C is an enlarged section on the line 4-4 of Fig. 1; and Fig. 5 is a longitudinal sectional view, partly broken away, illustrating the manner in which the curtain is attached to the roller.

Referring now to the drawings by numerals, 1 designates, as an entirety, the roller, and 2 the curtain. Said roller 1 comprises a pair of roller sections designated respectively 3 and 4, the former having an extension 5 integral therewith, said extension being smaller in size or of less diameter than the section 3 of which it is a part. Fixedly secured as at 6 to the said section 3 is a split sleeve 7, the bore of which is of a size corresponding to the size of the said section, the said sleeve extending beyond the end of the section to a point upon the same plane as the free end of the extension 5, this arrangement providing an annular way w thin which the other hollow roller section 4: 1s fitted. Said section 4: is longitudinally slotted as indicated at 8, within which slot a lug or block 9 of the extension 5 works, said lug or block preventing circumferential movement of one of the roller sections independent of the other. The terminals of the slot 8 when in engagement with the block 9 serve as a stop means whereby longitudinal movement of the sections 3 and 4 is limited 1n an adjusting operation, such adjustment being effected in a manner to be hereinafter fully described.

The curtain 2 is also divided intermediate its respective longitudinal edges to provide curtain sections 10 and 11, the former being attached as indicated at 12 to the section 3 of the roller and of such a width as to ex tend to a point adjacent the terminal of the extension 5, a wire 12 being arranged within the curtain top whereby to provide a stiffening or reinforcement for the extended portion of the curtain to prevent sagging or dropping thereof. Said wire strand is coiled at various points throughout its length as indicated at 13, through which coils the attaching means indicated at 12 extend. The detail manner in which the wire strand is arranged within the said top is best illustrated 1n Fig. 5 of the drawings. The section 11 of the curtain 2 is secured as at 14 to the section 4 of the roller, said section 11 extending beyond the inner end of the roller section 4, said extended portion of the curtain being reinforced or supported in a like manner to that just described in connection with the curtain section 10. By extending the sections 10 and 11 beyond the respective or adj acent terminals of the roller sections 3 and 4: it is apparent that one of the said sections, preferably 10, is disposed to overlap the other of the curtain sections whereby to effeet, in actual iractice, an unbroken curtain surface.

As a means whereby the free or lower end of the curtain may be adjusted to correspond to the adjustment of the roller 1, the weight rod 15 of the curtain is also divided, one of the sections thereof being longitudinally slotted as indicated at 16 to provide for the reception of a pin 17 rigid with the other of the sections of the said rod, said pin operating within the slot to maintain the sections upon the same horizontal plane and in a desired adjusted position.

To increase the length of the roller 1, that is to extend the same longitudinally, the sec tion 4 is moved relatively to the section 3,

causing the block 9 to be brought into engagement with one or the other of the slot terminals, in which event further longitudinal movement is impossible. The sleeve 7, taken in connection with the extension 5, supports the roller section 4 upon the same horizontal plane as the section 8, while the slit of the sleeve provides for sliding movement of the said section 4: without interference and without contact with the connecting means indicated at 14 in Fig. 1.

From the above,.taken in connection with the accompanying drawings, it is apparent that a curtain and roller constructed as above described may be used as a window covering for windows varying greatly in size; and that, if desired, a set screw may be used as a substitute for the pin 17 to in this manner fasten the rod 15 in its adjusted position.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings, and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with an extensible shade roller comprising a pair of relatively movable roller sections, of a shade comprising a pair of relatively movable shade sections, and means limiting movement of said roller and said shade sections, as and for the purpose set forth.

2. The combination with an extensible shade roller comprising a pair of relatively movable roller sections, and means carried by oneof said roller sections and engaging the other of the said sections to maintain the said two sections upon the same horizontal plane and against circumferential movement one independent of the other, of a shade comprising a pair of relatively movable shade sections, one of the said shade sections being attached to each of the respective roller sections, and means carried by said shade sections limiting movement of the said sections relatively to each other, as and for the pur 7 pose set forth.

8. The combination with an extensible shade roller comprising a pair of relatively movable roller sections, of a shade comprising a pair of relatively movable shade sections,said shade sections, being attached one toeach of the respective roller sections, the

said shade sections being disposed to overlap one another and to extend beyond the respec-, tive inner ends of the said roller sections to the respective shade sections, said strip sec' tions being adjustable relatively to each other to limit movement of the shade sections, as and for the purpose set forth.

4:. An extensible shade roller including a pair of relatively movable roller sections, an

extension formed upon the end of one of said sections, the other of the'said sections being hollow to receive the said extension, said hollow section having a slot formed therein, a block rigidwith said extension and fitting said slot, the terminals of the said slot limiting longitudinal movement of the section in an adjusting operation, a l0ngi-' tudinally slit sleeve rigid with said first mentioned section and embracing said last mentioned section, andv a longitudinally di vided shade, the sections of the said shade being attached, one to each of the respective roller sections, as and for the purpose setforth. 7 5. In combination, an extensible shade roller comprising a pair of relativelyv movable roller sections, a shade comprising a pair of relatively movable shade sections,

one shade section being attached to each of i the respective roller sections, and means limiting movement of said roller sections.

6. In comblnation, an extensible shade roller comprising a pair of relatively movable roller sections, a shade comprising a pair of relatively movable shade sections, said shade sections being attached, one to each of the respective roller sections, said shade sections being disposed to overlap one another and to extend beyond the respective inner ends of the said roller sections to which they are attached, means supporting said extended portion of the said shade sections, and means limiting movement of-the said roller sections in an adjusting operation.

7. In combination, an extensible shade roller comprising a pair of relatively mov able roller sections, a shade comprising a pair of relatively movable shadesections,

one shade section being attached to each of the respective roller sections, means cooperating with said roller to maintain the shade in adjusted position, means limiting movement of both the roller and shade in an adjusting operation, and means carried by one i of said roller sections and engaging the other of the said roller sections to maintain said sections upon the same horizontal plane, and

a against circumferential movement, one independent of the other.

8. The combination with an extensible shade roller, of a shade comprising a pair of relatively movable shade sections, and means attaching the shade sections to the roller.

9. The combination with an extensible shade roller comprising a pair of relatively movable roller sections, of a shade comprising a pair of relatively movable shade sections, the said shade sections being attached, one to each of the respective roller sections, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
